Product details

NAPA - NAPA Marine Starting Battery

A great day on the water can fall flat if you end up with a dead battery. Depending on your marine vessel’s needs and how it’s operated, different demands are placed on your battery. Whereas Deep-Cycle Batteries are engineered to provide a constant current over an extended time frame, NAPA Marine Starting Batteries provide a large burst of current for a brief time frame for engine starting capability.

Each NAPA Marine Starting Battery is made in the U.S., and backed by a 3-Month Free Replacement Warranty. They are crafted with calcium alloy, which prevents water loss and minimizes gassing. This ensures plenty of starting power right when you need it. These boat batteries are 100% maintenance-free, so you never have to top off or add any water. The cover is engineered for a precise, secure fit. The stainless-steel terminals install easily and remain corrosion-free.

Don’t spend your outdoor adventure replacing a worn-out battery! NAPA AUTO PARTS has all your battery replacement needs covered. NAPAOnline also carries a great selection of battery cables, battery hardware and related parts at great prices, so you can get your boat started and running great.
